to move thejplunger 27-to the left to the positionY shown in .Fig.7, whereas during the` secondhalf of thel revolutionjthe gear 25 engages the upper rackv29vand moves the plunger .-27 to thep'osition shownein Fig. 6.

Attached to the plunger27 -is a plate` 30 on l one side and on the other side is another plate exactly the same as the plate 30. These plates extend upward in front of the armature 31 of the magnet 32. These setting magnets 32 are the ones diagrammatically illustrated in Fig. 14 as 113 to 123. Between Y shoulder1 38 on the plunger 34. The dog 33 has a tail portion 39 so shaped as to fit the lower` part 'of the slot 35 when in normal position, as shown in Fig. 6. The sides of the slot 35 are so cut away that when the plunger 27 moves to the left, it willccarry the plunger 34 by means of the plates 30 through the connection with the dog 33. This condition will exist unless and until the plunger 34 comes in contact with some obstruction, at which time thegconnection between Vthe two will be broken, and the plunger 27 will continue to move to the left without the plunger 34 as shown in Fig. 7. The plunger 34 is arranged to move into and through the opening 40 in the galley 41. If there is suiiicient money 42 in the galley to extend Y above the lower part ofthe opening 40, the

. plunger. 34 will come in contact with Vthe yso coin and willbe arrested in its motion to the left, then as thev plunger 27 continues to thek left. the parts will assume the position shown in` Fig. Y7. That is, the dog will move out of the slot 35 and ride up. the side 36 to the position which is shown.y On the movement of the plunger 27 to the right, the shoulder 38 on the plunger 34 will come in contact with the underside of the dog 33 thereby rotating the dog in a clockwise direction around is pivot 43, and at the'same time moving the pivot 43 to the right relative to the plunger 34 until the tail 39 of the dog drops into the slot 35 as shown in Fig. 6. When in this position'7 the .plunger 34 is positively driven to the right by the plunger 27. Tn its course the plunger 34 strikes the armature 31 of the magnet and pushes the same to the right until all of the parts come to the position as shown in Fig. 6, at which time the gear 25 disconnects from the upper rack 29 and the shaft is automatically stopped as will be hereafter explained. The armature of the magnet illustrated in Fig. 6 is therefore shown in its inoperative position, the plates 30 abutting it to place the racks. beyond the reach of operative engagement by the gear 25; while the position of the armature lin Fig. 7 may be characterized as itsfsetting position, the point toV which it has given plunger 27 that preliminary advance which has enabled gear 25 to engage the rack and complete the entire reciprocation' thereof.

The gear wheel 19, mounted on shaft 16, has rigidly mounted thereon a clutch member 44 shown inidetail in Fig. 5. Mounted on the shaft 16 so as to revolve therewith is a clutch member 45. rThis memberl is rotatively attached to the shaft 16 by means'of a long key and is so arranged thatit is slidable along the shaft in a well known manner by means of an arm k46. The arm. 46 is rigidly attached to the member 47 which is pivoted at 48. Connected with the arm y47 is a member 49. This member 49` is provided with screw threads at one end and is atnuts 50. The opening in the member 47 is aV little larger thanthe stem ofthe member 49 so thata loose fit is providedt-o permit free operation. The member 49 extends through the standard 18'and pivotally connects with an electric knife blade switch 51,

ltached to the member 47 by the double-lock which switch blade is pivoted at 52. EX-

tending through an opening in the member 49 is a member 53 pivotedV at 54 in. the:

standard 18. Pivotally connected to the member 54 is a member 55, which in turn is pivoted to the member 56. The-member 56 is pivoted at 57 and lhas an end 58 projecting under the keyboard, 4. Arranged in the keyboardis a member 59, which contactsV with theend of the member 58,. The member 59 isoperated by a suitable push kev 60, which extends aboveV the top plate of .the keyboard 4. The member 59 is held in the position shown in Fig. 2 by means of: a coil spring 61. By operating the pushV key 60 the clutch member 45 is put into operative contact with the clutch member l4'4Vand atthe same time the knifeV blade switch 51 is closed to energize the motor to operate the machine. Referring againl to the Lclutch mechanism shown in Fig. 3, themember 45 has spring operated pins 62 held in the Vpo-V sition shown in Fig. 3 by means ofthe spring 63. The member 44 has cammed Y notches 64 therein as shown in F ig. 5. These notches are arranged .to coperate with the pins 62. Mounted in the member 47 1s a pin 65. Tn the surface of the clutch member 44 Vare two notches" 66, 180 from each other.

67. These cam surfaces are engagedby a pin 68 mounted in the member 47. As the gear 19 revolves, one of the cam surfaces 67 engages pin 68 and moves the member 47 together with the clutch member 45 and the member 49 to the right as shown in Fig. 3, thereby disconnecting the clutchmember 45 from the member 44 and at the same time opening the knife blade switch 51 to stop the motor. `.This brings Vthe member V47 directly over the 4clutch member 44 so that the pin 65 engages one of the notches 66 to stop the 'gear 19 at a predetermined point.. .i It is understood that Ithel shaft 21 makesl one- 47 moves .to' the 'left as shownin Fig. 3, so

that the pin is movedout of the plane of the member 44, so that the same may rotate.

Mounted on an extended hub of the gear 19 isadisk69 as sho-wn in Figs. 2an'd. 3. This disk 69 has two notches 70 therein which are 180o apart., SeeFigs. 2, 3 and 4. Mounted on the standard 18 is a knife .blade switch 71. This switch blade has a projection 72 thereon, which lcoperates with the notches in the disk 69; .The switch blade is pivoted at 73 and has a tail piece 74 thereon. The switch member 71 when'closed connects contacts 75 which Vcompletes a commoncircuit'to the operating magnets. 4The switch blade 71l is biased to closing` position-by means of the spring 76. i y

The tail piece 74Sof thek switch blade 71 extends through'a slot in the member 77. This member'77 depends from a shaft x78 extending across the machine. This shaft is j ournaledin the side frame membersg2. Suitably attached to this shaft 78 is -an apron 79. Arranged on the front of the machine is al shortage key 8O havinga stemV extending through an elongated hole in the member 77 -The pin 81 is fastened in this by means of look nuts 82 on each side of the member 77.y 5

They purpose of` the arrangement which was previously described is to automatically open the circuit common to all ofthe operating magnets as soon as the motor begins to operate, so that the combination set up on` the keyboard cannot be changed after the machine is set in operation. vThis is accom?V plished'by vthe cam surfaces or notches 7 0 in the disk 69, mountedA on the shaft 16 throwing the knife blade switch 71 out of `contact with the contacts 75 vas shown in Fig. 2. If, during a cycle ofthe machine, it happens thatthe coins in one or more ofthe stacks corresponding to one of the' selected plungers isv below a predetermined point, as .for

' instance that shown Vin Fig. 8, the plunger` 34, being permitted to pass through the opening 40 in thel galley 41, the dog 33 is brought into contact with the apron -79 which tilts the shaft 7 8v together *K with thel arm 77 into the position shown in Fig. 8. This causes the push-button and its stem 81 to be moved' to theleft as representedk in Fig. 2, so that theta-ilpiece 74 of the knife blade switch71 is caught in theupper side of the slotted-opening in the member 77 and the knife blade switch held open, so that is impossible to -a further operation vof the machine without first pushing intheshortage key so as torelease theknifev ating magnets. This `warning signal may be blade switchto close the circuit 4'ofthe oper# given' before the money 'is entirely exhausted fromfthe stack-and this may takeplace 'atany'point depending upon the, position vof the opening40fin the galley 41. i V';

Mounted in the sideframes 2 is a shaft 83. Mounted on; .the shaft 1837isv an apron 84. This' apron extends fa" substantialv diss` tance from the shaft and as shown in Figs. 2, 6, 7 and11 is so placed as to contact withV "the 'members 30 extending below the ,plunf gers 27. 'Pvotallygattachedto the pivoted shaft is :remember-85', which in turn is pivvot'edtoa pin-86 which: extends through the e main frame" ofthe machine andwhich has" on L the outervend thereof an error key 87. Mounted on vthis pin 8,6 is a compression spring 88. YThe :obj ect of this arrangement is to .jcorrect any mistakes whi'chmay have` been made and rwhich have vbeen discovered before the motor has been started'. 'If sucha mistake has occurredafter 'the magnets have been energized the error key 87'will be pushed in, which will rotate-the vshaft83` v with its apron, which apron will-.engage the membersBO of lall-the plungers which have been selected" and move. them back to'their. V'

The second depression'89 is shown, which .is v. the position the plunger takes when" it is actuated` bythe magnet but before it," is moved by the shaft 21.-

Referring tov Figs. 9 and sent partial views of' thegalley, thel stacks 92 and 93 take twenty-dollar gold pieces, Y f

stacks94 and 95 take teni-,dollar gold-,pieces 10, which repre and the stacks 96 and97 take iivc-dollargold j pieces The .stackY 92 'delivers twov20sineach operationl of :the plunger, whereas the stack ..93 delivers YAonly. one. The v,same is"v true of the stacks 94 and 95 respectively and. alsoofthe stacks 9.6 and 97 respectively'. `.1

lThe distance v-fro'ni the` bottom 98 of the stack 92 to [the apron 99 which extends en` tirely across the galley, varies withthe. dif-` ferent staeks; It is thisdistance which .dei termines the numberofpieces ithat will-be ejected by leachr plunger, as statedabove.l This permits thecoin to dropdown so that the' plunger y27 in certain of` the "stacksgen- `gages two y,coins instead of one asitdoes in Y 100 'Y for steadying the plungers27 in position.' i l l on'the stem 102. ln each case, these com-V side of all electro-magnets.

certain others all of 'which is eXplained below. ,f f 1 ln Fig. 13 are shown two keys 100 and- 101. The key 101 is shown depressed, i whereas thepother is in its normal position. fr Each key comprises a push-button suitably mounted on a stem 102.

This stem extends through the plates 103 and 104 which are of insulating material. Located between these plates and around the stem is a spring 105, one end of which rests against the plate 104 and the other end against the sleeve 106. Mounted on the lower end of the stem 102 is a button of conductingV material 107. This button contacts with the spring contacts 108 and 109, and the lower end of the stein engages the spring contacts 110, which contacts are connected to the wire forming the common side of the circuit of all electroby an insulating plate 111, and may be. fastened to this plate in any suitable,mannen- As shown in Fig. 14, the keys may have contacts ranging in number from 1'to 8, not counting the common contactsl110, which contacts are used in all of the keys. Two contacts 110 are used in each case'merely for the purpose of preventing transverse strain mon contacts are Velectrically connectedtogether. l/Vhen thebutton 107 isin the position of the key 101, both contacts 108 and 109 are electrically connected with the common contact 110, This is true with respect to all of the contacts when there are two, as shown in Fig. 13, or more than two as for instance, .as representedby the $38.91 key, as shown in large figures on F ig. 14. 1n that case, when the key is pressed, the five contacts shown on the $38. key Vare connected with the common side and Vthe five contacts of the 91 key are also connected with the common side. Each of the contactsv 108 and 109 ofllig. 13 and the othercontacts in all other keys are connected with an operating magnet. This electrical diagram is shown in Fig. 14 in connection with the keys representing $38.91, and the circuits are as fol-r lows: y

From the positive main through the wire 112 to the common wire 113 connected to one Y By reason of the' fact that the key 38V is pressed, a circuit is created through the magnets 114, 115, 116,

117 and v118 by bringing the contacts 108 and 109 into contact with the common contacts 110, as shownin Fig. 13. By reason of the fact that the key 91 is pressed, the magnets 119, 120, 121, 122 and 123 are energizedfor the same reason. This causes the plungers operating on the twenty-dollar, ten-dollar, live-dollar, two one-dollar and two `Fifty-cent pieces to be placed in operative relation to the gear sectors 25 on the shaft 21. ln the cents section of the keyboard the magnets Vwise placed in operative condition.

operatino` on theA stacks or receptaclesL con'-y taining fty-cent, twentylive-cent, ten-cent, five-cent and one-cent pieces will be likethis vhas been accomplished, the push-button 60 is pressed down which starts the motor After and connects the clutch, and-which in turn causes one revolution of the shaft 21 and a complete operation of each of the above designated. plungers, thereby delivering to the conveyer belt 124 the coins to the value of $538.91, and which coins are delivered bythe belt to the delivery coin spout 125, shown in Fig. 1. Shown in Fig. 1 is a fuse`plug'126, having fuses 127V therein. Also a snap switch 128 is shown in the'sideframe mem'-V sov ber 2 of the machine for placing thefcurrent on Ythe machine. Y

Referring to Fig. 2 in connection with 4the push-button 60 are provided two contacts 129, which areladapted to be connected ytogether electrically bythe metal button r130; onthe stem 59. These! contacts complete a' circuit through the magnet-'131, F igs.'1 and 3 which has an armature 132 mechanically connected to the member 47.' 1f it is desired to operate this part of the machine electrically, the parts 53, 54, 55, 56, 57 and' 58 will be eliminated and the member-47 moved by the magnet 131. This arrangement is particularly useful when the keyboard is in one place and the other part of the machine is 'in another place. ll/hen the machine Vis manufactured these Vcontacts 129 and the magnet 131 are provided eXtra,"so that the machine may be readily converted frommechanical operation to electrical operation without the taking apart of the machine vand the adding of any (eXtra parts, as these eXtra elements in no way interfere with. the operation of the machine mechanically.

The galley 41 is held in place on the ma-Y chine by providing on the upper' part of the machine and attached 'to' the side frame members 2, a brace member 133. f This brace 133 has cut therein two notches 134, as"

shown in Fig. 1.k VAttached 'to the back of the galley are two `projections 135 in the' taclied, and may be with its contents, placed( in a vault or other suitable place for safe keeping. rThis conserves'space by making' it unnecessary to place the Vwhole machine in suoli place for safe keeping'.v It is .underiut stoodlthat. 'the galley maybe .made .of any size 'dependent Auponthe use to 'which the machine fis adapted-and 'itscontentsv may, fiunder such '.circumstances, be many.- thou- -sands of dollars.vv

`.The keyboard is usually :provided `with 210 keys. The-hundred. oir-the left,V asshown in Fig. V14 represent what may be called the dollar keys, while the. hundred on the right of Fig. 1-4 are the cents keys. The ten ke'ys .in the center arechange keys and may bewiredup so as to give the Vchange'ina'variety ofdenominations. The wiring for' the fivedol-lar lkey and the. onedollar key is shown in dotted lines inAFi-g. 14, and forsi-mplicity in the:drawings,-Ighave not shown'the wiring of the other keys, as the wiring` may be varied according to the desires 4of the owner I of the machine and will beV perfectly appar- 20 ent from the wiring which I have shown. The wiring of the five-dollar. key is fas :follows: A common contact isy connected tothe contact of all itheother keys.V Thethree *four one-.dollar and two fty-cent pieces. The one-'dollar -key is wired asv follows:

remaining contacts are.' connected' 'respectively .tov the magnets 11, v10 and 9', thus giving the five dollars change in the form of The contact is connected l.to the contact of all the other keys. The fiver'emaining contacts are connected respectively to the magnets 8, .7', 6', 5 and4, `thus giving the change, inthe form 'of one vfifty-cent, one

Ftwenty-five cent, two ten-cent and one fivec'ent piece. It is 'obvious from this that the various change keysmaylbe wired up so as Vtovgive the change'in any denominations de'- 1 sired; 'It is 4also understood that anyone of .the keys shown on the keyboard may be provided witha greateiwor less'lnumber of contacts-*than that shown in'the drawing in Fig. 14. They mayf-likewise be wired 'up in various ways toproduce the-coin orjchange in any form, and it isqunderstood that the showing in Fig. 14 is merely for the purpose ofV illustration and innite variations. thereof maybe made.

The keys lare-each''provided witfha suitablebutton with the indication thereon bef ing representative Vof the amountof change each key represents.. Thisjis a well known .feature in keys of this'character. The operation Of my machine isas follows: 1

The switch-128 is closed and the keysnrepfl presenting the desired'amount are operated,

.and inthe operationvof the machine 'lwill describe it as if the keys representing $38.91 y have been operated, and on'this assumption the keys representing. these figures would be .pressed down eitherA4 at the same time or suc-V cessively. The-key for .$88.00 closes the circuitv through the Amagnets114f 115, 116,117 'and 1-18 `andthe keyfor- 91e 'closesthe cirp cuit .throughthe magnets 119, 120, 121, l22,

This throws the tail part 74 down and the switch l0A starts on to disk 69 and is 'thus opened. When the money in ene of the stacks is below the 'opening 40, the plungers 34, which 7l rides up out of notch 70 as the motor Vits starting-point, the switch-will be again automatically'closed by the spring 76.

In the event that the'wrong key has .been

Apressed'and the mistake has been discovered before the push-button `(5() ris pressed, the correction' kmay be madeA by pressing the push-button 87, as shown in Fig. `11, thus rotating the shaft 83 t0 theright and bringing the `apron 84 into contact with vall of V"the plungers 27, which have been setforward-on the previous set-up, thereby pushing the plungers back into their original inoperative'position. The desired keys may pressed and the operation proceeded with. v v

'While `I have described the foregoing' machine somewhat in detail, it isfunderstood,

of course, that I am not by any means limited to the exactV details as described. .Neither do I desire to be limited to the exact number of keys shown'on thegkeyboard nor to the number of receptacles in the galley nor the particulara'rrangement of the receptacles in the galley,`because, if-it is desired to make a machine larger than that merely duplicating the parts shown and widening out the machine, as well as by increasing the length of the receptacles in the galley.
